Abstract
It was studied that with a yield of 92%,N,N′-diisopropylcarbodiimide was prepared by oxidative dehydrogen-sulfidation from N,N′-diisopropylthiourea and chlorodiethylamine.N,N′-diisopropylthiourea was synthesized with a 94.8% yield by reflux dehydrogen-sulfidation from isopropylamine and carbon disulfide.Meanwhile,it was also studied that chlorodiethylamine was recovered to make diethylmine recycled and cost decreased.
